That depends. It sounds like a non-human existence, and I have no desire to be anything other than a human being.
I'm sure that some (many?) people have a kind of self-hatred, and want to be something else. Paul talks about, in Heaven, being given a new body, which is beautiful and doesn't have sin-nature. Such a body would, I suppose, find joy and/or peace in Heaven a completely natural state.
Since I do not share that self-hatred, I would rather vacillate between suffering and joy/peace if that is the inevitable result of the sort of being that I am. Just as I would accept occasional illness interrupting my usual physical health.
Furthermore, let's say that there is some person that I could identify that is clearly happier than I am. And let's say that I was given the opportunity somehow to be that person in every respect, so that I was not myself anymore. Even my memories and personality would disappear and be replaced by my new existence as that other person. As an example, the traitor in the first Matrix movie asks Agent Smith to make him a famous, rich, and happy movie actor, and to completely erase his memories of his miserable life. He thinks that this is a bargain.
If I were given that opportunity, I would refuse.
